To /r-ZZ 7071/0717] it 71u03/ concern.-

Be itknown that 1, JONAS NILssoN, a citizen of the United States, and a resident of Fremont, in the county of Dodge and State of Nebraska, have invented a new and Improved Locomotive Fire-Box, of which the following is a full, clear, and exact description.

, The object of this invention is to so construct the fire-box and connected parts of a locomotive as to enable the contents to be dumped at will from the cab. To this end I employ in connection with the dumping ashpan an operating' device for the grate and ashpan, such device passingl into the locomotivecab, so as to be readily operated b v the enginedriver or his assistant.

The invention comprises certain novel features of construction and arrangement of parts, as will be hereinafter fully described, and pointed out in the claims.

Reference is to be had to the accompanying drawings, which form a part of this specification, in which drawings like characters of reference indicate like parts in the several views, and in which- Figure 1 is a side elevation showing a locomotive equipped with my improvement and illustrating the manner of dumping the firebox while the locomotive is on a trestle or staging, thus admitting of throwing the ashes directly into a cart drawn under the trestle or staging. Fig. 2 is an enlarged sectional view of the rear end of the locomotive equipped with my invention, the section being taken on the line 2 2 of Fig. 3. Fig. 3 is a sectional plan on theline 3 3 of Fig. 2. Fig. 4 is a crosssecti'on on the line et 4 of Fig. 3. Fig. 5 is a fragmentary section on the line 5 5 of Fig'. 3, and Fig. 6 is a fragmentary side view showing the devices for sustaining the ash-pan.

As best shown in Fig. 2, the grate is made up of a number of rockably-mounted bars 10 and a rear section 11, pivotally mounted on a transversely-extending axis 12. Below the grate is located the ash-pan 14, which is pivotally mounted at its front end on a transverse axle-shaft and arranged to swing downward in dumping position, as indicated by full lines in Fig. 1 and by dotted lines in Fig. 2. The grate-,bars 10 are each connected with an arm 16, and to said arm is joined a link 17, which extends rearward to an arm 18, fast on a vertical shaft 19, extending up into the locomotive-cab. At its Lipper end said arm is provided with a handle 2O to facilitate rocking the shaft, and by this rocking movement the grate-bars 10 may be turned into active or dumping position, as desired. The rear grate-section 11 is held in horizontal or active position by means of arms 21, attached to a rock-shaft 22. This shaft is mounted transversely of the engine and has one end provided with an arm 23, to which is connected a link 24. Said link extends rearward into the cab and isjoined to a lever 25, mounted therein. This enables the rear section 11 of the grate to be raised or lowered, as desired.

The ash-pan 14 is held in raised position by a U-shaped sling 26, the arms of which are hingedly mounted at the sides of the [ire-box through the medium of pins 27, connected to brackets 28. (See Figs. 3 and 6.) As shown in Fig. 6, the brackets 28 are provided with horizontally-arranged slots 28 and screws 28b extend through the slots and hold the brackets in place. With this construction the sling can be readily adjusted to the desired position. The sling 26 is designed to swing under the rear end of the ash-pan when the ash-pan is raised, thus holding it securely in its position. Connected to the middle portion of the sling is a rearwardly-projecting arm 29, to which a lever 30 is articulated by a link 30, pivoted to both parts. Said lever is conveniently fulcrumed, for example, as shown in Fig. 2, and extends up into the cab. Connected with the rear portion of the ash-pan 14 are one or more chains 31, these chains extending' up over drums 32, fastened on a transverse shaft 33. The shaft is revolubly mounted in suitable bearings 34C at the rear of the fire-box and is provided with a gear 35, meshed with a spurl 36, fastened on a short shaft 37, located within the locomotive-cab. Said shaft 36 is revolubly mounted on bearings 38 and is provided with a hand-crank 39, facilitating the operation of the shaft. In this manner` the drums 32 may be made to raise or lower the chains 31 and the attached ash-pan.

L10 indicates a foot-dog adapted to engage the lever 30 to hold the same in its forward position, thus keeping the sling 26 engaged with the ash-pan, and 4:1 indicates pawl-andratchet devices for holding the shaft 37, gear 36, and connected parts in the position desired.

The manner of using the invention will, it is thought, be clearly understood. Then the parts are adjusted as shown by the full lines in Fig. 2, the locomotive-furnace may be operated in the usual manner, and when it is desired to dump the grate this may be brought about by the operation of the handle 20 and IOO IOS

IIO

lever 25, thus dropping the coals and ashes on the ash-pan 14. To dump the ash-pan, the lever 30 should be thrown to move rearward the sling 26 and disengage the same from the ash-pan, thus allowing the ash-pan to drop by gravity. The ash-pan may be returned to its active position by the operation of drums 32, winding up the chains 31, as before explained.

rIhis arrangement enables the contents of the fire-box to be dumped conveniently by the engine-driver without leaving the cab and without necessitating some one reaching under the lire-box, as itis now necessary with engines ordinarily equipped. Fig. l also shows an advantageous use of the invention, in which the locomotive is run on a trestle and thefashes dumped directly into a cart instead of into the usual cinder-pit of a roundhouse, from which the ashes will have to be afterward shoveled or otherwise removed.

Various changes in the form, proportions, and minor details of. my invention may be resorted to at will Without departing from the spirit and scope thereof. Hence I consider myself entitled to all suc'h variations as may lie Within the terms of my claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent4 1. The combination of an ash-pan mounted to swing, a swinging sling arranged to engage under the free portion of the ash-pan to support the same in active position, an arm connected with the bottom portion of the sling, a link pivoted to said arm, and a lever pivotally connected with said link.

2. The combination of an ash-pan mounted at one end to swing in an arc, a U-shaped sling located at the free end of the ash-pan and adapted to inclose the same to hold it in active position, means for mounting the sling to swing, and means for operating the sling to disengage it from the ash-pan, said means comprising a lever and a link pivoted thereto and to the sling.

3. The combination of an ash-pan mounted at one end to swing in an arc, a sling mounted at its upper end to swing in an arc, said sling being adapted to embrace the free end of the ash-pan to sustain the same, means for moving the sling to disengage it from the ash-pan, and means for raising the ash-pan into position to be engaged by the sling, said means for moving the sling comprising a lever and a link pivoted to the lever and having pivotal connection with the sling.

4. The combination of an ash-pan mounted at one end to swing, a sling pivotally mounted at its upper end and arranged to swing under the free end of the ash-pan when the latter is raised, and means for moving the sling to disengage the ash-pan, the said means comprising a rearwardly-extending arm connected to the lower end of the sling at the middle portion thereof, a link pivotally connected at one end with said arm. and a lever pivoted to the other end of said link.

5. The combination of an ash-pan mounted at one end to swing, a U-shaped sling having its side arms pivotally mounted, the sling being arranged to swing under the free end of the ash-pan when the latter is raised, means for raising the ash-pan into position to be engaged by the sling, and means for moving the sling to disengage it from the ash-pau, said means comprising an arm connected to the middle portion of the sling, a link pivotally connected at one end with said arm, and a lever pivotally connected with the other end of said link, and a foot-dog for engaging the le- Ver.

6. The combination of an ash-pan mounted to swing, a swinging sling arranged normally to engage under the free portion of the ashpan to support the same in active position, means for moving the sling to disengage it from the ash-pan, said means comprising a lever and a link pivoted at one end to the lever and at the other end to the sling, means for raising the ash-pan into position to be engaged by the sling, and means for holding the lever in position to keep the sling engaged with the ash-pan. V
